Soft and chewy vegan hot cocoa cookies with mini marshmallows and chocolate chips.
Preheat your oven to 180℃/350℉ (or 160℃/325℉ for fan or convection ovens).
Line a large baking tray or two with baking paper.
In a small mug or bowl, mix together the flax seeds and water. Let it sit for 5 minutes or so until thick. Set aside for now.
In a large bowl, mix together the margarine, caster sugar and soft light brown sugar. Stir in the flax seed mixture along with the vanilla extract.
Add the self-raising flour and cocoa powder to the bowl and mix. When it's starting to stick together, use your hands to press it all into a ball of dough.
Add the chocolate chips and marshmallows and gently knead them into the dough with your hands.
Divide the cookie dough into 12 pieces and roll each piece into a ball. Gently flatten the balls to make discs that are roughly 1 inch thick.
Place the cookies on the tray, leaving a bit of space in between to allow for spreading. Top with extra marshmallows and chocolate chips if desired.
Bake for 10-12 minutes, until the cookies are firm around the edges and wobbly on the inside. They'll look a bit underbaked but will firm up as they cool so trust the process!
Leave the cookies to cool completely before removing them from the tray.
